SPECIFICATION forming part of Letters 'Patent No. 407,841, dated JulySO, 1889.

Application filed December 19, 188'?. Serial No. 258,269. (No model.)

To all whom it may concern,.- v,

Be it known that l, O'r'ro SCHIMANSKY, a citizen of the United States,residing at Sandusky, in the' county of Erie and State of Ohio, haveinvented certain -new and useful- Improvements in Machines forCuttingHops, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to new'and useful improvements in machines forcutting hoops, and the obj eet of the invention is to construct amachine especially adapted -ior cutting barrel-hoops from boardsorvplanks; and to this 1 5 end the machine is provided with afeed-table,

upon which the plank is fed by a suitable set of feed-rollers to a 'setof saws on a revolving arbor, which cut the plank into strips, and atthe same time a series of cutters, held in cutzo ter-heads, securelyfastened upon the sawarbor, plane the upper faces et the stripsrounding. The lower edges of the strips are similarly rounded by acutter-head revolving below the strips, and then a series of saws on aninclined arbor divide e.-.chstrip into two hoops, while each strip issecurely-held by guides. l My invention consists in thepeculiarjconstruction and arrangement of the parts, all as 3o more fullyhereinafter described, and speci fically point-ed out in the claims.

In the drawings which accompanythis specification, Figure 1 is asectional side elevation of my improved machine. Fig. 2' is a planthereof. Fig. Il is a cross-section on line 0J fr, Fig. 2. Fi g.l lis across-section on iincy y, and Fig. 5 is a cross-section of one of thccutterheads.

A is a frame ot' my innachinc, which snp- 4o ports the operatingpartsthereohjand this frame is provided 'with thc feed-table li, to oneedge of whiclis secured the longitudinal guide C. A

D are feed-rollers arranged inpairsfof any snit-able construction,adapted tdfe'ed planks. -The upper roll of cach pair is a liverolia-ni".

is secu red in vertically-slidi ng bearin gs. ,\vhich are acted on bysuitablesprings-or otherwise,

fo-canse the rollers to press upon the plank'` with suicientfforce andcausethe feed-roll- 5o ers to feed the plank forward.

E area series of .revolving` saws secured in the arbor F, and upon thesamearbor are secured'the cutter-heads Gr, each .of which is providedwith a .sct of knives H adjustably secured thereto, as shown in Fig.'5.The cutter-heads and saws alternatewit-h each other, and they are rmlyheld together by means of the clamping-collars o; and by means ot' thepin or bolt b, passing through all of the 6o cutter-heads and saws andentering the sockets in the clampin g-coll ars, allvso arranged that thecutter-heads divide the plank into. strips, and at the same timethe'individual cutterheads between thesaws plane the upper face 6 5 ot'each strip rounding, as shown.- A little to the rear of this cutterheadand below the table is secured the cutter-head J on the revolving arborI, and this cutter-head consists ot 'a' series of'sectional"cutter-heads ot'the 7o Asanne 'kind vas the cutter-head G, beforedescribed. The function of the cutter-head J is to plane the lower edgesof the strips in the saine way a's 'the upper edges are planed.Slight-ly to the rear of this cutter-head, and above the table, arearranged guide-rollers K, which are `carried by the vertically-slidingblock L, which is sleeved upon the guide L and acted on by the springL'Z, to press the rollers on top of the strips. These rollers con- Sosist of the individual rollers r and the disks' (l alternatingtherewith, all so arranged that the rollers .c press upon the top of thestrips, while the disks d guide thc saine in a longitudinal direction.Below these guide-rollers K and corresponding with the disks d thereofare placed the guide-strips c in thc bed of thc table, which, projccting upwardly therefrom, actin connection with the disks dtoguidc thestrips. In the rear of these guide-rollers 9o .fucI arranged a set otsaws M, secured upon an inclined saw-arbor N, .and these saws project upthrough thc table suiiicie'ntly to divide each strip into two hoops, asshown in dot-tod .lines in Fig. 4. 1 95 In practice, it will befseenthat the portion of the plank which rest-s againstgthc longitudinalguide C is carried. under thc saws E,

which divide that portion of the plank into a nn'xnber ofstripaandat'the Sametime plane each strip on the outer edge by means ofthe intermediate cutters. The cutter-head J then similarly planes thestrips on the under side, and then the gnide-rollers,in. connection withthe guidestrips e :in the bed, guide these strips to the-inc1ined saws,which cut'each strip into two hoops. It will be seen that if a plank isfed upon the table Iwhich is of greater width than comes within thereach of the saws it is severed entirely and completely, and as soonasthis portion is thus separated the attendant at the rear end of themachine caniinmediately push it back to enable the operator at the frontend to feed it again 'until the whole plank is out up into strips. Theoperation of the machine thus enables the operators to use their time tothe best advantage in the interval while the strips are being out upinto hoops.

It will further be observed that the combination ol the saws andcutterheads into one composite cutter-head gives additional strength toboth the saws and cutter-heads, and inakes all irregular workimpossible. By using saws to separate the plank into strips the stripshave parallel sides, and they are therefore more easily guided to thesecond set of saws than if the plank were separated into strips bycutters, where the sides naturally are of oval shape.

As it often happens that by imperfections in the planks disturbances arecaused in the machii'iery, l provide the feed-rollers with a reversingsliding clutch Q., as shown, which is acted on by the lever P iuproximity of the operator at the front end of the machine, so

that at an instant he may reverse the feed as the loose pulleys R R runin opposite dil-cetions, andv thereby prevent accident.

I am aware that it isnot new to divide planks into strips, and thenredivide each strip into two hoops; but

Vhat I claim as my invention is l. In a hoop-cutting machine, acuttelhead consisting` of a rotary arbor carrying rotary saws to dividethe plank into strips, cutterheads placed alternately between the sawsand in the same relative position thereto and cured upon a common arborand arranged to cut a plank into strips and plane the upper edges ofsaid strips, and a lower planer-head provided with cutters arranged toplane the lower edges of the strips, substantially as dc scribed.I V

3. I nl a machine for the purpose described, the combination of the mainframe, feedtable, feed-rollers, combined saws and planerheads, the setofinclined saws, and the guidestri ps in the planer-bed, all arranged forjoint operation, as set forth.

In testimony whereof I aiix my signature, in presence of two witnesses,this 13th day of October, 1887.
